“…MSCs are stem cells of stromal origin characterized by their multipotency with the ability to self-renew [2] [3] and differentiate to diverse cell phenotypes such as osteoblasts, chondrocytes, adipocytes, fibroblasts, tenocytes [4] [5], hepatocytes, neural cells and/or epithelial cells [6]. Due to their crucial regenerative, reparative, angiogenic and immunomodulatory properties, MSCs have generated increased interest in a variety of biomedical disciplines and several areas of experimental and clinical applications [2]. Surely, marrow MSCs (BM MSCs) have been the most widely studied; however MSCs can be also isolated, with similar but not identical features, from different tissues including umbilical blood cord (UCB MSCs), placenta, adipose tissue (AT MSCs), trabecular bone, dental pulp and peripheral blood (PB MSCs) [7]- [12].…”
